DE2340640B2 - Silo for nude pasta - Google Patents

Description

The invention relates to a silo according to the preamble of claim 1.

When producing nude-shaped pasta, a corresponding dough is continuously processed depending on the the type of pasta to be produced is pressed into shapes. Then the pasta is cut and dried. Since the packaging machines are used to pack the finished pasta in portions work rhythm different from the previous production process and generally a larger one Have performance than the upstream production line, technical development has gone before the Packing a silo to be provided.

In the case of the production of spaghetti, it is known to create such a silo by having the Support rods, on which the spaghetti already hang from drying, in a corresponding rack lines up. With increasing production output, however, one soon comes to a very large number of Support rods, for example several thousand, which is no longer economical.

Furthermore, a silo of the type mentioned is known (DT-AS 12 63 644). With this well-known silo Relatively large and high lu shafts serve as storage tanks, several of which are next to each other in the Support frame are arranged and occupy their entire height. As a result, the fragile nude-shaped pasta when filling and emptying these shafts over relatively long distances be poured, and it is necessary to the discharge product stream of the individual shafts to interrupt packing several times. Although through cascade-like installations in the shafts for a reasonably gentle bulk flow is provided, there is still the in this known silo Risk of broken pasta in not inconsiderable quantities. This is extremely disadvantageous as the broken pasta, especially if it is fragments of long pasta, in the packaging machines transversely and may make it necessary to stop them from time to time. Such business interruptions put a strain on the profitability of the entire plant. In addition, pasta packaging, which contain fragments, unfavorable for sale.

The invention is based on the object of creating a generic silo in which as possible little pasta breakage occurs.

The features serving to solve this problem are in the characterizing part of claim 1 specified.

In the case of the silo according to the invention, the individual storage containers can therefore be considerably smaller Height than with the generic silo, and still the height of the available Space can be used even better. The pasta can be in optimal, comparatively Store small portions, and a level control of the storage container, as it is with high storage containers is required is dispensable. Since the storage tank is completely emptied at once there is no longer any need to interrupt the flow of evacuation product. Relatively low Storage tanks are insensitive to contamination. Finally, the filling of the storage container does not have to be more take place at great heights.

In the silo according to the invention, nude-shaped pasta can be stored in practically any desired length, for example spaghetti, croissant noodles, mussel noodles and the like.

Preferred developments of the invention are specified in the subclaims.

The invention is illustrated below with the aid of several exemplary embodiments tiltable storage containers explained in more detail.

F i g. 1 shows schematically a silo for sliced pasta. A number of support frames 1 are one Stack 2 lined up. The support frames 1 can be moved on rails 4 by means of rollers 3. On the left On the image side, a support frame Γ with an elevator 5 or its driver 6 is gradually moved onto the rails 4 lowered. Above the stack 2 there is a tier 7.

The support frames 1 have a number of storage containers 8. In stack 2, the support frames are filled Storage container stored, in the stack 7 the empty. In the same way as filling the storage tank, the Emptying a single support frame 1 "by a second Aufzag 9 with driver 10 step by step raised. Each of the storage containers 8 of the support frame 1 ″ is brought against a tilting device 11, which brings the storage tank to be emptied. After emptying the lowest storage tank of the Support frame 1 ″, the support frame is placed on the upper rails 12 and against the stack 7 of the remaining frame with empty storage bins pushed.

F i g. 2 and 3 show a support frame 1 on an enlarged scale. The support frame 1 is through a closed frame 13 is formed for five identical storage containers. Each storage container 8 is divided in length by dividing plates 14 into a larger number of compartments. Each storage container 8 is mounted via two pivot pins 15. The center of gravity 5 of a single storage container 8 is on the left Page with respect to the pivot pin 15 of FIG. 2. A cam 16 prevents the storage container from tipping over: rs counterclockwise. The compartments of the storage containers formed by the separating plates S4 are in the Length slightly larger than a single spaghetti.

Of a cutting machine 17 (Fig. 1) reach the spaghetti on a bucket conveyor 18, also called carousel 8 in the reservoir The contained in each bucket elevator cups 19 optimum portions A case with bottom flap 21 such as in a cascade-like feed tube 20 of the height the top storage container 8 of the stack 2, that is to say about halfway up the silo, is gently brought into the storage container 8.

The portions A are fed from the silo through a transfer chute 24, a bucket elevator 26 with cups 25 directly to the packaging machine.

The function of the silo for sliced pasta is only the following with reference to Figs. 1 to 4:

After the cutting machine, portions A, A ', A "■ ■ ■ are formed. These portions A are brought into the bucket elevator cups 19 according to a certain weight or volume The portions A are poured through the feed chute 20 in a manner that is gentle on breakage.

Control means (not shown) lower the support frame Γ step by step and bring it into the filling position, so that one storage container 8 after the other can be filled through the filling shaft 20. For this purpose, the bottom flap 21 of the filling shaft 20 is opened and the contents are unloaded into the storage container 8 provided. The bottom flap 21 is closed and gives the impulse for lowering the support frame Γ by a further step. In this way, the portion A ', A " , etc. is also brought into the corresponding storage container 8.

After the storage container 8 of the support frame Γ is filled, it is placed on the rails 4 and the next support frame is taken into the elevator 5. The full support frame Γ can push against the stack 2 with a small force, possibly by hand will.

The entire system is advantageously designed in such a way that, for example, products can be filled into the storage container 8 during an entire night shift. The filling of the storage container 8 is completely independent of their emptying. As is known, the emptying of the storage container 8 can take place much faster than the filling due to the modern high-performance packaging machines. Therefore an independent elevator 9 is arranged on the evacuation side. The cycle of the elevator is controlled directly by the packaging machine in that individual portions A, A ', which correspond to the volume of the transfer shaft 24 acting as a storage container, are called up. If the transfer shaft 24 is empty (FIG. 5), which can be determined without complicated aids, the elevator 9 is raised by one storage container division. Up to this point in time, a single storage container 8 has not performed any relative movement with respect to the support frame 1 ″, since it is held in a fixed position by the specific arrangement of the center of gravity or the cam 16. The walls of the storage containers 8 on the emptying side are essentially parallel to the support frame 1.

If there is a full storage container 8 opposite the tilting device 11, as with reference to FIGS. 5 and 6 is shown, a lever 23, which is mounted on a shaft 27, by a piston 28 in the clockwise direction panned. The lever 23 pushes against the cam 16, as shown in Figure 5, and the Storage container is tilted. In and of itself, even with a slight turning movement, individuals would Spaghetti fall from the storage container 8. The top, downward-moving edge of the Storage container 8 is therefore close to an arcuately curved storage wall 29 downwards turned. This retaining wall holds the spaghetti back in the storage container 8 until the cam 16 is open sew the lower side of the support frame 1 and the

the entire content is emptied into the transfer shaft 24. After the specified emptying time has elapsed the lever 23 pivoted back. Since the center of gravity of the storage container 8 is arranged on one side, it has the tendency to return to its original position. After the last storage tank has been emptied 8 of the support frame Γ it is lifted onto the upper rails 12 and back to the stack of empty storage containers brought. From the transfer chute 24 the spaghetti fall into bucket elevator beakers 25 of an emptying bucket elevator 26th

After the cutting machine 17, portions A are formed. Portions of the order of 4 to 10 kg are very advantageous. It is even possible to store the portions in the silo in the exact weight required for packaging. A very advantageous embodiment, and also a very economical solution, results from the division of the storage container 8 by dividing plates 14 into approximately 8 to 10 compartments, each compartment having the dimensions of a cut length. Although the pasta could in principle be filled directly into the storage container 8 by the cutting machine 17, it is advantageous in many cases to interpose a bucket elevator 18, also known as a carousel. In a very advantageous embodiment, the bucket elevator 18 has more bucket elevator cups 19 than the number of compartments of the storage container 8 formed by the dividing plates 14 in the horizontal plane. In this way, all compartments of a storage container 8 can be filled in one operation. One advantage lies in the fact that the individual movement sequences can be carried out more slowly and thus more reliably and also more gently.

In a continuation of the inventive concept, the support frame 1 can be shifted on the rails 4 and 12 via an upper stepping mechanism, FIG. 8, and a lower stepping mechanism, FIG. 9. A drive rod 30, which extends over the entire length of the silo and is supported at several points, is moved back and forth by a piston 31 in a selectable cycle by a distance X> T. The support frames 1 have a curved track 32 and a driver cam 33. The curved path 32 has an ascending part of the curve and a descending part of the curve. The cam 33 has a stop side 34. On the drive rod 30 levers 36 are rotatably arranged via bearing journals 35. A bearing roller 37, which slides over the cam tracks 32, is attached to the end of the lever. Each lever has a longitudinal reinforcement rib 38 and an eye 39 approximately in the middle. A driver 40 is mounted on the eye 39 via a pivot pin 41. The driver 40 has a roller 42 on the lower end side, which, however, moves in the same vertical plane as the roller 37 or the cam track 32. The driver 40 also carries stops 43 and 44 which act against the longitudinal reinforcement rib 38. The driver 40 can only perform a small movement relative to the lever 36. The driver 40 has a thickening 45 on the right side, which leads to a shift in the center of gravity on this side. The driver 40 wants to rotate counterclockwise. The stop 43 strikes the longitudinal reinforcing rib 38 without any other force intervention. The lower step sound system differs from the upper one in that an additional tension spring 46 wraps the driver 40 in a defined l.agu, which is caused by the weight of the upper one.

10 and 11 show the operation of the longitudinal drive in two successive phases. The main purpose of the stepping mechanism is to add a single support frame independently of the stack move, so without applying force to the stack itself. A single support frame should be like the full fed or removed from the empty stack. This means that the forces of movement can be small

ίο be held. A support frame is after moved others. If the first support frame is removed, the step-by-step mechanism should replace the second Slide the support frame in place of the first, the third support frame in place of the second to the whole stack is shifted around a support frame. The entire stack is always in this way, be it for one Empty or ready for filling.

The F i g. 10 now shows two support frames IV and IVI. The stepping mechanism is put into operation. The piston 31 pulls the drive rod 30 by one step X to the left. The lever 36 is in the lowest position, since there is no guide for the bearing roller 37. The driver 40 is in the closed position with respect to the lever 36. The drive rod 30 only pulls the support frame IV with lever 36, driver 40 and driver cam 33 to the left. At the same time, the lever 36 'with the drive rod 30 is also moved to the left. However, since the roller 37 'is raised by the curved path 32 and remains, is sicr

jo also the driver 40 'in a higher position. Wit from Fig. 11, the roller 42 'passes over the cam 33' without exerting a direct force on the support frame IV1. The support frame IVI therefore remains in place. After the piston 31 the

J5 has moved the drive rod 30 to the left: by the distance X , the entire stepping mechanism is brought back again at the same distance X. The lift 36 is raised with the roller 37 over the curved track 32. The support frame IV remains. The lever 36 'wire is retracted the same distance. The roller 37 'falls down over the last piece of the cam track 32, see that the lever 36' is moved to the right in the lowest position. The driver 40 ', which is withdrawn with the lever 36, slides over the path of the cam; 33 'until the roller 42' comes into the engagement position on the right-hand side. After the complete pushing back, the cycle starts again. The driver 40 moves between the cams 33 and 33 'during the second advance phase. Dei driver 40 thus does no pushing work. De: driver 40 ', on the other hand, fetches the support frame IVI and moves it into the previous position of the support frame; IV. In this way, any number of supporting frames can now be pushed forward step by step

v, but normally only one support frame needs to be moved. During normal operation, the stepping mechanism could be kept in motion with a minimum of energy.

The support frame 1 wiser, above curved tracks 32 to

mi cam 33 as well as curved tracks below Cam on, as shown in FIG. 8 and 9 are shown. Preferably, the upper cam tracks are 32 µm Cam 33 arranged laterally and the lower cam tracks in the middle around cams.

ι.-. Furthermore, it is very advantageous to give both the storage container 8 and the retaining wall 29 according to FIG. 7 a toothing that fits into one another. This resulted in the topmost spaghetti / wischei jamming

Storage container 8 and retaining wall 29 are prevented, they also remain in an exactly parallel position. In addition, relatively large manufacturing tolerances can thus be achieved be respected.

12 and 13 show a support frame 50 with storage containers 51. The support frames 50 point downward a sliding roller 52 and are attached to a hook 53. The freely swinging support frame 50 can be attached with a rope or a chain.

This solution is more suitable for smaller silos. Again, a larger number of frames are stacked strung together, similar to that in Fig. 1 schematically shown execution. A single frame can be used with known lifting devices that may be present, be brought into the required positions. The possible inclination of the is also very advantageous here whole frame, be it for filling or for emptying, like with one shown in empty position Storage container 51 'is shown.

14 shows a particularly advantageous application example of a silo according to the invention.

The pasta is fed from a dryer T into a cutting machine C , which feeds portions A directly into the silo S via a carousel Ki . A second; Carousel K2 takes over the portions A of the silo unc it feeds a Vortrichter in the Verpackungsma machine P. It is apparent from this Fig. 14, is that the "bestimintc from the dryer 7 ceiling height i through the silo economically utilized and still can

to portions with simple aids at a convenient height in the silo 5 and out of this can be removed. The individual portions are poured a few times and only over minimal heights and can always stay together. Breaking the spaghetti is almost completely avoided and damr also operational disruptions and interruptions.

The silo itself can be brought into a room climate that is favorable for the dried spaghetti, or at least the full stacks can be surrounded by a protective skin.
